​Mizuki is a serious, diligent girl who rarely shows her emotions, no matter the situation. Although she may come off as cold-hearted, this isn't the case - She just doesn't know how to express her emotions, something she wants to improve upon. Mizuki also has a puppet, whose name is "Little Mizuki". What's interesting about this puppet is that it can speak, but no one is sure about whether it's Mizuki doing ventriloquism, or if it's just technology doing the speaking.​

She enjoysmaking creative dishes for her friends, giving people nicknames and also boxing. Abe Rika also has 2nd grade English Certification.
